Angular2声明指令的选择器以要求输入文本

Question

I have just created a number directive : 我刚刚创建了一个数字指令：

@Directive({
  selector: '[ngModel][number]'
})
export class NumberDirective  {...}

I would like my selector to be even more specific and requires a text input : 我希望选择器更加具体，并且需要输入文本：

<input type="text" [(ngModel)]="..." [number]="...">

You can use attribute selectors with value 您可以将属性选择器与value一起使用

selector: 'input[type="text"][ngModel][number]'
